Some Viewsonic DLP projectors have this issue. It happens when the DMD chip goes bad. You need to replace the DMD chip. Google "Viewsonic DMD chip replacement". This is not localized to Viewsonic projectors.

1,white spots appeared on screen,means the DMD is broken,you need a new DMD.
2,the projector running off after only a few minutes,means the Inductor (Sensing element),near the Color Wheel. Use a cotton swab moistened with alcohol to wipe the Inductor.

Have a good day!

Hi,

I noticed you have a DLP projector. I have a Optoma EzPro 756 which is also a DLP projector.
I notice white "blobs" on the screen when there is a black screen. It is caused by dust getting into the optical block not the lense. If you are comfortable with opening up the projector, you could gently blow out the optical area with compressed air, GENTLY so you don't dislodge any components, and see if that helps. I seems to be a common problem with DLP projectors a few years old. If there are sharp focused dots on the screen then most likely, it could be some pixels starting to go bad like dead pixels on a computer screen. That problem is pretty much irreversible.

Hope this helps,

Yellow band on the edge of screen


Hi chucri

This is most definitely not a lamp problem.

If a yellow colour in either stripes or blotches occur it is a blue LCD polarizer that needs replacement.

NEC VT-47 picture problem


Hi there

This is unfortunately not the bulb or the lens that causes these blotches , but the LCD's.

It is normally only one LCD panel that has burnt and then need replacement.

I would suggest you have this replaced at an authorised dealer as this is quite a tricky process !

VT45 Projector: Blue pixels throughout screen


If the problem is what I describe as a blue haze over the entire image projected, I was told this is a defect in the cable - we have a Dell Video Projector 2300 - and it takes only a dell VGA cable.

So, the problem is in the cable - solution is replace cable.
